Might want to try the LME49810, mono so easier to layout a board. Seems to be easier to get fully stable too. The mono version of the LM4702 is not far away from release. Also might be easier to work with. Laying out a stereo board can be a little bit of a pain. IF you use Darlington devices, don't try to use more than one device per side in the output stage or you may never get it stable.

I won't. I'm following the reference design to the letter, aside from decreasing the voltage rails (which I have been told won't cause any problems aside from a lower power output.)

Was wondering about issues like:
1. Stability (board layout and other factors)
2. Current limit of OP stage (STD03=15A, 2SB/D=10A) and it's effect on quality
3. DC servos, speaker protection etc - what did you do here?
